Rocket (Def Leppard) Easter Egg - Backwards Message

If you play Rocket by Def Leppard backwards, they say clear as day "We're fighting with the Gods of War." Also if you listen carefully during the instrumental part of Rocket backwards, you can hear other song titles in there. I've also noticed that Def Leppard wrote Rocket fowards and backwards on the single to form the shape of a Rocket. Maybe that was a clue?
